*Which ethics committee needs to review studies involving human samples depends on where they are collected from, whether they are anonymous, and whether they have been collected with consent for use in research. Where samples have not been collected with consent for use in research, even when they are anonymous to the researcher, an application will need to be submitted to an NHS REC. Certain tissue banks can also issue ethical approval as part of the application process for obtaining human samples, providing these have been collected with consent for use in research. If studies involving samples falls under this category, please check the approval with the BSREC Secretary BSREC at warwick dot ac dot uk before the project begins.
